fix(explore): generate correct chart export url when using legacy api

[lucapazz]

SUMMARY

When exporting data via CSV/JSON/Excel from a Time-series Table chart you get a 404 "Page not found" error.
The issue is caused by the malformed export URL, where the origin is duplicated.
This PR removes the origin from the generated URL before passing it to the SupersetClient, which in turn adds it when making the request.
